Detailed Implementation

[0016] This disclosure provides embodiments of a communication method, a communication device, a communication system, and a storage medium. In a first aspect, embodiments of this disclosure provide a communication method executed by a terminal, the method comprising: Determine the total first CSI processing unit occupied by multiple CSI reports within the same time unit; In response to the fact that the first CSI processing unit is greater than the second CSI processing unit supported by the terminal, at least one CSI report with a lower priority among the plurality of CSI reports will not be updated according to the priority of each CSI report among the plurality of CSI reports.

[0017] In the above embodiments, when the first CSI processing unit occupied by multiple CSI reports is greater than the second CSI processing unit supported by the terminal, the terminal can choose not to update the lower-priority CSI reports among the multiple CSI reports according to the CSI priority. By not updating the lower-priority CSI reports, resource conflicts of CSI processing units can be avoided.

[0018] In conjunction with some embodiments of the first aspect, in some embodiments, the plurality of CSI reports include a first CSI report and a second CSI report, wherein the first CSI report is the CSI of at least one first cell, and the second CSI report is the CSI of at least one second cell; wherein the first cell is a non-serving cell of the terminal; and the second cell is one of the serving cell and the non-serving cell of the terminal.

[0019] In the above embodiments, the terminal can measure and calculate the CSI of the non-serving cell and the CSI of the serving cell, thereby enabling the terminal to perform fast cell handover based on the measured CSI report and ensuring the terminal's communication capabilities.

[0020] In conjunction with some embodiments of the first aspect, in some embodiments, the first CSI report includes at least one of the following: Precoding Matrix Identifier (PMI); Rank identifier RI; Channel Quality Identifier (CQI); Layer identifier LI; Channel State Information Reference Signal Resource Identifier (CRI).

[0021] In conjunction with some embodiments of the first aspect, in some embodiments, the second CSI report includes any one of the following information: Null value, CRI-RI-PMI, CRI-RI-First-level codebook identifier i1, CRI-RI-i1-CQI, CRI-Reference signal received power RSRP, CRI-Signal-to-interference-plus-noise ratio SINR, Synchronization signal block SSB-Index-RSRP, SSB-Index-SINR, CRI-RI-LI-PMI-CQI, CRI-RSRP-Index, SSB-Index-RSRP-Index, CRI-SINR-Index, SSB-Index-SINR-Index, Time-domain channel characteristics TDCP.

[0022] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: The priority of each CSI report is determined based on at least one of the following: the bearer mode indication parameter, the indication parameter for whether to carry the first reporting quantity, the corresponding cell index and the serving cell limit of the terminal, the CSI report configuration identifier, and the maximum number of CSI reports configured for the terminal.

[0023] In the above embodiments, the terminal can determine the priority of each CSI report. Based on the priority of the CSI reports, when there is a resource conflict in the CSI processing unit, it can clearly identify which CSI reports need to be updated and which do not need to be updated, thereby resolving the problem of resource conflict in the CSI processing unit.

[0024] In conjunction with some embodiments of the first aspect, in some embodiments, the first CSI report has a higher priority than the second CSI report.

[0025] In conjunction with some embodiments of the first aspect, in some embodiments, the second cell corresponding to the second CSI report is the serving cell of the terminal.

[0026] In the above embodiments, in the scenario where the first cell corresponding to the first CSI report is a non-serving cell and the second cell corresponding to the second CSI report is a serving cell, the priority of the first CSI report is set higher than that of the second CSI report in advance. This enables the terminal to update the CSI of the first cell in a timely manner, ensuring the real-time accuracy of the first CSI report. Moreover, since the first CSI report of the first cell can be obtained in advance, the terminal can be directly scheduled according to the first CSI report after the terminal switches to the first cell, without the need to measure the first CSI report after the switch. This enables the terminal to switch quickly, ensures timely data transmission, and reduces data transmission latency.

[0031] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: The system receives the second information sent by the network device and determines the reference signal resources for CSI measurement of the cell corresponding to each CSI report based on the second information.

[0032] In the above embodiments, the terminal can determine the reference signal resources for CSI measurement of the cell corresponding to each CSI report based on the second information, so that CSI can be measured through the reference signal resources. Moreover, the priority of CSI is related to the number of reference signal resources, which can provide a basis for determining the priority of CSI.

[0077] Figure 1 This is a schematic diagram of the architecture of a communication system according to embodiments of this disclosure. Figure 1 As shown, the communication system may include a terminal 101 and a network device 102.

The access network device may include at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), wireless backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a wireless fidelity (WiFi) system, but is not limited thereto. In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs. In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility. It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0079] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection. The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), NewRadio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G). In NR, especially in frequency range 2 (above 6GHz), high-frequency channels attenuate rapidly. To ensure coverage, beam-based transmission and reception are required. Currently, to address rapid handover, Rel-18 has investigated L1 / L2 trigger mobility (LTM). This involves the base station configuring multiple candidate cells for the terminal. Each candidate cell is configured with synchronization signal blocks (SSBs). The terminal can measure the SSBs of the candidate cells and report the measurement results of the SSBs corresponding to M candidate cells. Each candidate cell reports the measurement results of N SSBs, such as the Layer 1 Reference Signal Received Power (L1-RSRP).

[0080] Based on this measurement result, the base station configures a target cell for the terminal, as well as a Transport Configuration Indicator (TCI) state identifier (ID) corresponding to the target cell. The Reference Signal Resource (RS) indicated in the TCI (state) identifier (ID) can be the SSB of the target cell, or a Tracking Reference Signal (TRS) that has a quasi-co-location (QCL) relationship with the SSB of the target cell.

[0081] If the terminal switches to the target cell, the target cell becomes the new serving cell. Further, the terminal needs to first obtain the reference signal resource (RS) configuration for CSI (channel state information) measurement and the CSI reporting configuration information of the new serving cell. Then, it performs CSI measurement on the new serving cell and reports the CSI to the new serving cell. The new serving cell then schedules the terminal and transmits data based on the obtained CSI. However, this results in significant data transmission latency. If the new serving cell does not obtain the terminal's CSI and directly schedules the terminal based on the default CSI, a poor default CSI will lead to a low terminal transmission rate, while a high default CSI will result in a low decoding success rate, still resulting in a low transmission rate.

[0082] To address the above issues, a proposal has been made that allows the terminal to obtain the CSI of candidate cells in advance. However, how to handle scenarios where multiple CSI reports, including the CSI of candidate cells, need to be calculated simultaneously becomes a problem. The method proposed in this disclosure can resolve resource conflicts in CSI processing units by not updating lower-priority CSI reports when the number of CSI processing units occupied by multiple CSI reports exceeds the number of CSI processing units supported by the terminal.

[0083] Figure 2A This is an interactive schematic diagram illustrating a communication method according to an embodiment of this disclosure. For example... Figure 2A As shown, this disclosure relates to a communication method for a communication system 100, the method comprising: Step S2101: The network device sends the first information to the terminal.

[0084] In some embodiments, the first information may be used to determine multiple CSI reports that the terminal needs to process within the same time unit.

[0085] Optionally, the multiple CSI reports that need to be processed can be understood as multiple CSI reports that need to be calculated or updated.

[0086] In some embodiments, the first information may be used to indicate multiple CSI reports that the terminal needs to process within the same time unit.

[0087] In some embodiments, the network device may send first information via Downlink Control Information (DCI) signaling. Optionally, the terminal receives DCI signaling and obtains the first information.

[0088] In some embodiments, the network device may send first information via Radio Resource Control (RRC) signaling. Optionally, the terminal receives RRC signaling and obtains the first information.

[0089] In some embodiments, the network device may send first information via Medium Access Control Control Element (MAC CE) signaling. Optionally, the terminal receives MAC CE signaling to obtain the first information.

[0090] In some embodiments, the first information includes CSI report configuration-related information.

[0091] In some embodiments, the first information may include the identifiers of the cells corresponding to each of the multiple CSI reports. The terminal determines the multiple CSI reports based on the cell identifiers. For example, one or more non-serving cell identifiers may correspond to one CSI report, while the serving cell identifier may correspond to one CSI report. As another example, the first information may include a set of multiple cell identifiers, with different sets corresponding to a single CSI report.

[0092] In some embodiments, the first information may include the reporting volume corresponding to each of multiple CSI reports. The terminal determines the multiple CSI reports based on the reporting volume. For example, the reporting volume may include one CSI report corresponding to L1-RSRP or L1-SINR, while the reporting volume may include another CSI report corresponding to PMI, RI, CQI, etc.

[0093] In some embodiments, the first information may include type identifiers corresponding to multiple CSI reports. The terminal determines the multiple CSI reports based on the type identifiers; for example, a CSI report with the type identifier 'typeI-SinglePanel' corresponds to one CSI report, and a CSI report with the type identifier 'typeII' corresponds to another CSI report. In some embodiments, the first information may include indication information for the multiple CSI reports; for example, the indication information includes "0" and "1", where "0" may indicate CSI measurement of the terminal's serving cell, and "1" may indicate CSI measurement of the terminal's non-serving cell.

[0094] In step S2102, the terminal determines multiple CSI reports that need to be processed within the same time unit based on the first information.

[0095] In some embodiments, time units may include, but are not limited to, subframes, slots, symbols, etc.

[0096] In some embodiments, multiple CSI reports may include a first CSI report, a second CSI report, a third CSI report, and so on. These multiple CSI reports need to be calculated within the same time period, for example, within the same symbol.

[0097] In some embodiments, the terminal can determine multiple CSI reports that need to be processed within the same time unit based on the cell identifiers corresponding to the multiple CSI reports included in the first information.

[0098] In some embodiments, the terminal may determine multiple CSI reports that need to be processed within the same time unit based on the type identifiers corresponding to the multiple CSI reports included in the first information.

[0099] In some embodiments, the terminal may determine multiple CSI reports that need to be processed within the same time unit based on the reporting volume corresponding to the multiple CSI reports included in the first information.

[0100] In step S2103, the network device sends second information to the terminal, which is used to determine the reference signal resources for CSI measurement corresponding to each CSI report.

[0101] In some embodiments, the second information may include reference signal resources for CSI measurement for each cell in multiple CSI reports. The terminal can perform CSI measurement on the cell based on the reference signal resources for CSI measurement.

[0102] In some embodiments, the second information may be CSI measurement configuration information sent by the network device, based on which the reference signal resource for each CSI report that needs to be measured can be determined.

[0103] In some embodiments, the CSI measurement configuration may include at least one of the following: Configuration information for CSI-RS resources may include, for example, resource periodicity: CSI-RS resources can be periodic, semi-persistent, or aperiodic. The type of measurement resources may also include resources for channel measurements and resources for interference measurements.

[0104] The configuration information reported by CSI may include, for example, report type, report content, report frequency, and report timing. The report type can be periodic, semi-persistent (based on PUCCH or PUSCH), or aperiodic. The report content consists of the reported parameters, such as the Precoding Matrix Indicator (PMI), Rank Indicator (RI), Layer Indicator (LI), and Channel Quality Indicator (CQI).

[0105] The codebook information reported by CSI may include, for example, codebook type and codebook restriction subset. The codebook type specifies the type of codebook used for reporting, such as Type I, Type II, or Enhanced Type II codebook. The codebook restriction subset limits the range of precoding matrices that the terminal can report for CSI.

[0106] Configure power control parameters during CSI measurement and reporting; Configure limitations on CSI measurements and reports in the time and frequency domains, etc.

[0107] In step S2104, the terminal determines the third CSI processing unit for each of the multiple CSI reports, and determines the total first CSI processing unit occupied by the multiple CSI reports based on the third CSI processing unit.

[0108] In some embodiments, the third channel state information processing unit (CSIProcessing Unit, CPU) corresponding to each CSI report includes a third CSI processing unit required to calculate or update each CSI report.

[0109] In some embodiments, the third CSI processing unit is determined based on at least one of the following: The number of cells corresponding to each CSI report; The number of Channel State Information Reference Signal (CSI-RS) resources used for CSI measurements in each cell corresponding to each CSI report; The number of ports of the CSI-RS resource corresponding to each CSI report; The number of channel measurement resources used for CSI measurements in each cell corresponding to each CSI report; The type of each CSI report; The number of reports corresponding to each CSI report.

[0110] In some embodiments, the number of cells corresponding to each CSI report is positively correlated with the size of the CSI processing unit; that is, the more cells corresponding to a CSI report, the larger the CSI processing unit required for that CSI report.

[0111] In some embodiments, the number of CSI-RS resources for CSI measurement corresponding to each CSI report is positively correlated with the size of the CSI processing unit. That is, the more CSI-RS resources corresponding to the CSI report, the larger the CSI processing unit required for the CSI report.

[0112] Optionally, a CSI report may correspond to one cell or different cells for CSI measurement using CSI-RS resources. In this case, the number of CSI processing units required for the CSI report may only be related to the number of CSI-RS resources used for CSI measurement, without needing to further consider the number of cells. However, another CSI report may correspond to N cells, with each cell having a one-to-one correspondence with the CSI-RS resources used for CSI measurement. For example, if the number of CSI-RS resources for CSI measurement corresponding to each cell is M, then the number of CSI processing units required for this CSI report is related to both the number of cells N and the number of CSI-RS resources M corresponding to each cell. For instance, the number of CSI processing units required for this CSI report may be directly proportional to the number of cells N and the number of CSI-RS resources M corresponding to each cell.

[0113] In some embodiments, the number of ports of the CSI-RS resource corresponding to each CSI report is positively correlated with the size of the CSI processing unit. That is, the more ports the CSI-RS resource corresponding to a CSI report has, the larger the CSI processing unit required for that CSI report. For example, the size of the CSI processing unit required by a CSI-RS resource with 4 ports is greater than the size of the CSI processing unit required by a CSI-RS resource with fewer than 4 ports.

[0114] In some embodiments, the number of channel measurement resources for CSI measurement corresponding to each CSI report is positively correlated with the size of the CSI processing unit. That is, the more channel measurement resources corresponding to the CSI report, the larger the CSI processing unit required for the CSI report.

[0115] Optionally, a CSI report may correspond to one cell or different cells for channel measurement resources used for CSI measurements. In this case, the number of CSI processing units required for the CSI report may only be related to the number of channel measurement resources used for CSI measurements, without needing to further consider the number of cells. However, another CSI report may correspond to N cells, where each of the N cells has a one-to-one correspondence with the channel measurement resources used for CSI measurements. For example, if the number of channel measurement resources used for CSI measurements for each cell is M, then the number of CSI processing units required for this CSI report is related to both the number of cells N and the number of channel measurement resources M corresponding to each cell. In other words, the number of CSI processing units required for this CSI report may be proportional to both the number of cells N and the number of channel measurement resources M corresponding to each cell.

[0116] In some embodiments, different types of CSI require different sizes of CSI processing units.

[0117] In some embodiments, the number of reports per CSI report is related to the size of the CSI processing unit. The more reports per CSI report, the larger the required CSI processing unit; conversely, the fewer reports per CSI report, the smaller the required CSI processing unit. The combination of reports per CSI report also affects the size of the CSI processing unit; different combinations of reports result in different required CSI processing unit sizes. The computational complexity of each CSI report's reports also affects the size of the CSI processing unit. The greater the computational complexity of each CSI report's reports, the larger the required CSI processing unit; conversely, the smaller the computational complexity of each CSI report's reports, the smaller the required CSI processing unit.

[0118] In some embodiments, the terminal can perform CSI processing unit calculations on each of the multiple CSI reports to determine the third CSI processing unit occupied by each CSI report. Optionally, the multiple CSI reports include a first CSI report and a second CSI report. Optionally, the first CSI report is a CSI report of at least one first cell, and the second CSI report is a CSI report of at least one second cell, wherein the first cell is a non-serving cell of the terminal, and the second cell is one of the terminal's serving cell and non-serving cell.

[0119] In some embodiments, the first cell is not currently the serving cell of the terminal; that is, the first cell is currently a non-serving cell of the terminal. It is understood that when the terminal determines the reference signal resources of the first cell, the first cell is not yet the serving cell of the terminal.

[0120] In some embodiments, the first cell can be one of the terminal's candidate cell, neighboring cell, and target cell. It is understood that when the terminal determines the first reference signal resource, the first cell is not yet the terminal's serving cell. For example, the first cell can be the cell to which the terminal is about to handover; after the terminal hands over to the first cell, that first cell becomes the terminal's serving cell.

[0121] In some embodiments, the second CSI report may be a CSI report of the serving cell or a CSI report of a non-serving cell. For example, the second CSI report may be a measurement report of L1-Reference Signal Received Power (RSRP) or L1-Signal-to-Noise-and-Interference Ratio (SNIR) of a non-serving cell.

[0122] The following explanation uses the third CSI processing unit occupied by the first CSI report as an example to illustrate how to determine the third CSI processing unit occupied by multiple CSI reports: In some embodiments, the third CSI processing unit occupied by the first CSI report relates to at least one of the following: The number of first cells corresponding to the first CSI report; The number of CSI-RS resources used for CSI measurements corresponding to the first CSI report; The number of ports of the CSI-RS resource corresponding to the first CSI report; The number of channel measurement resources used for CSI measurements corresponding to the first CSI report; The first type of CSI report; The number of reports submitted by the first CSI.

[0123] In some embodiments, the type of the first CSI report may include, but is not limited to, the following types set in the codebook: single-panel type I, multi-panel type II, port selection type II, type II, enhanced type II, and enhanced type II.

[0124] In some embodiments, the type of CSI reported by the first CSI can be a single CSI with wideband frequency granularity (CSI). single CSI with wideband frequency-granularity).

[0125] In some embodiments, the amount of data reported in the first CSI report can be any of the following: 'CSI-RS Resource Indicator (CRI) - Rank Indicator (RI) - Precoding Matrix Indicator (PMI) - Channel Quality Indicator (CQI)', 'CRI-RI-Layer Indicator (LI)', 'CRI-RI-LI-PMI-CQI'.

[0126] In some embodiments, different reporting volumes of the first CSI report have different effects on the third CSI processing unit occupied by the first CSI processing unit. For example, the third CSI processing unit occupied by the reporting volume of the first CSI report being one of 'CRI-RI-PMI-CQI', 'CRI-RI-LI', or 'CRI-RI-LI-PMI-CQI' is different from the third CSI processing unit occupied by the reporting volume of the second CSI report being any of 'CRI-RSRP', 'CRI-SNIR', 'SSB-Index-RSRP', 'SSB-Index-SINR', 'CRI-RSRP-Index', 'SSB-Index-RSRP-Index', 'CRI-SINR-Index', or 'SSB-Index-SINR-Index'.

[0127] In some embodiments, the process of determining the third CSI processing unit occupied by the first CSI report may include: The number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement corresponding to the first CSI report, the number of ports of the CSI-RS resources corresponding to the first CSI report, the number of channel measurement resources for CSI measurement corresponding to the first CSI report, the type of the first CSI report, and the reporting volume corresponding to the first CSI report are determined. Based on at least one of the above information, the third CSI processing unit occupied by the first CSI report is determined.

[0128] In some embodiments, the number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement, the number of ports of the CSI-RS resources, the number of channel measurement resources for CSI measurement, the type of the first CSI report, and the reporting volume corresponding to the first CSI report can be determined based on the CSI measurement configuration corresponding to the first CSI report of the network device.

[0129] In some embodiments, after determining the third CSI processing unit occupied by each CSI report in the plurality of CSI reports, the third CSI processing units occupied by each CSI report can be summed to obtain the total CSI processing units occupied by the plurality of CSI reports, which are referred to as the first CSI processing unit in this embodiment of the disclosure.

[0130] In some embodiments, the total number of first CSI processing units occupied by multiple CSI reports can be determined based on the number of CSI reports. Optionally, a limit on the number of CSI processing units occupied by each CSI report can be pre-configured or agreed upon. Further, the first CSI processing units occupied by multiple CSI reports can be determined based on the number of CSI reports and the limit on the number of CSI processing units occupied by each CSI report.

[0131] In some embodiments, the total resources occupied can be determined based on the CSI measurement configuration information of multiple CSI reports, and the total first CSI processing unit occupied by the multiple CSI reports can be determined based on the total resources occupied.

[0132] In some embodiments, the number of CSI reports for each type can be statistically obtained based on the types of multiple CSI reports and the quota (e.g., size) of CSI processing units for each type. Further, based on the number of CSI reports for each type and the quota of CSI processing units for that type, the total first CSI processing units occupied by the multiple CSI reports can be determined. The CSI processing unit quota for each type can be configured by the network or agreed upon by a protocol.

[0133] Step S2105: In response to the first CSI processing unit being greater than the second CSI processing unit supported by the terminal, the priority of each CSI report among the multiple CSI reports is determined.

[0134] In some embodiments, the second CSI processing unit supported by the terminal may be determined based on protocol agreements, network configuration, or the terminal's capabilities.

[0135] In some embodiments, if the first CSI processing units occupied by multiple CSI reports within the same time unit are greater than the second CSI processing units supported by the terminal, that is, the first CSI processing units required by the terminal exceed the second CSI processing units that the terminal itself can provide, the terminal can determine the priority of each CSI report among the multiple CSI reports.

[0136] In some embodiments, the bearer mode indication parameter is based on each CSI report. y Whether it carries the indicator parameter of the first reported quantity k Corresponding cell index c and the serving cell limit of the terminal CSI report configuration identifier s The maximum number of CSI reports configured for the terminal. At least one of the following is used to determine the priority of each CSI report.

[0137] In some embodiments, the priority of each CSI report can be determined according to the following formula: (1) in, This indicates that non-periodic CSI reporting is performed on PUSCH. for aperiodic CSIreports to be carried on PUSCH); This indicates that semi-continuous CSI reporting is being conducted on PUSCH. for semi-persistent CSIreports to be carried on PUSCH); This indicates that semi-continuous CSI reporting will be conducted on PUCCH. for semi-persistent CSIreports to be carried on PUCCH); This indicates that periodic CSI reports will be made on PUCCH. for periodic CSI reports to be carried on PUCCH).

[0138] This indicates that the CSI report carries L1-RSRP or L1-SINR ( (for CSI reports carrying L1-RSRP or L1-SINR); among which the following reports will carry L1-RSRP or L1-SINR: 'CRI-RSRP', 'CRI-SNIR', 'SSB-Index-RSRP', 'SSB-Index-SINR', 'CRI-RSRP-Index', 'SSB-Index-RSRP-Index', 'CRI-SINR-Index', 'SSB-Index-SINR-Index'.

[0139] This indicates that the CSI report does not carry L1-RSRP or L1-SINR ( for CSI reports not carrying L1-RSRP or L1-SINR).

[0140] c c represents the serving cell index.

[0141] Indicates the serving cell limit of the terminal ( is the value of the higher layer parameter maxNrofServingCells The service cell limit can also be understood as the maximum number of service cells.

[0142] s Indicates the CSI report configuration identifier ( s is the reportConfigID ); This indicates the maximum number of CSI reports configured for the terminal. The maximum number of CSI reports configured for the upper-level parameter (maxNrofCSI-ReportConfigurations) is the value of this parameter. isthe value of the higher layer parameter maxNrofCSI-ReportConfigurations ).

[0143] The following explanation uses the priority of the first CSI report as an example to illustrate how to determine the priority of multiple CSI reports: Whether the first CSI report carries an indicator parameter for the first reported quantity. k =1; The CSI report configuration identifier corresponding to the first CSI report: In scenarios where CSI reports are configured using LTM-CSI-ReportConfig, s Indicates the CSI report configuration ID of LTM LTM-CSI-ReportConfigID ;otherwise, s This indicates the CSI report configuration identifier.

[0144] The first CSI report corresponds to In scenarios where CSI reports are configured using LTM-CSI-ReportConfig, The maximum number of CSI reports configured for the upper-level parameter LTM (maxNrofLTM-CSI-ReportConfigurations). Otherwise, Indicates the maximum number of CSI report configurations.

[0145] Cell index corresponding to the first CSI report c In scenarios where CSI reports are configured using LTM-CSI-ReportConfig, c This is the index value of the serving cell configured in the configuration report. Otherwise, c This indicates the cell index of the serving cell for the terminal.

[0146] Based on the above information and formula, the priority of the first CSI report is determined.

[0147] In some embodiments, both the first cell and the second cell are non-serving cells of the terminal, and the priority of the first CSI report and the second CSI report can be determined based on the above information and formula (1).

[0148] Optionally, the first CSI report is a CSI of a non-serving cell, and the reported quantity in the first CSI report is at least one of PMI, RI, CQI, LI, and CRI; the second CSI report is also a CSI of a non-serving cell, and the reported quantity in the second CSI report is L1-RSRP or L1-SINR. All other values ​​in the formulas corresponding to the first and second CSI reports are the same, only the reported quantity differs. Based on the above formula (1), the priority value corresponding to the first CSI report is determined to be greater than the priority value corresponding to the second CSI report. Since a larger priority value indicates a lower priority, the priority of the first CSI report is lower than the priority of the second CSI report.

[0149] Optionally, the first CSI report is a CSI report for a non-serving cell, and the reported quantity in the first CSI report is at least one of PMI, RI, CQI, LI, and CRI; the second CSI report is also a CSI report for a non-serving cell, and the reported quantity in the second CSI report is also at least one of PMI, RI, CQI, LI, and CRI. The cell indices corresponding to the first CSI report and the second CSI report are different. For example, the cell index corresponding to the first CSI report is 0, and the cell index corresponding to the second CSI report is 1, while all other values ​​in the formula are the same, only the cell indices are different. Based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report. The larger the priority value, the lower the priority; therefore, the priority of the first CSI report is greater than the priority of the second CSI report.

[0150] Optionally, the first CSI report is a CSI report for a non-serving cell, and the reported quantity in the first CSI report is at least one of PMI, RI, CQI, LI, and CRI; the second CSI report is also a CSI report for a non-serving cell, and the reported quantity in the second CSI report is also at least one of PMI, RI, CQI, LI, and CRI. The LTM CSI report configuration IDs corresponding to the first CSI report and the second CSI report are different. For example, the LTM CSI report configuration ID corresponding to the first CSI report is 0, and the LTM CSI report configuration ID corresponding to the second CSI report is 1. All other values ​​in the formula are the same, only the LTM CSI report configuration IDs are different. Based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report. Since a larger priority value indicates a lower priority, the priority of the first CSI report is greater than the priority of the second CSI report.

[0151] It should be noted that the above only gives an example where only one value of each of the values ​​in formula (1) corresponding to the first CSI report and the second CSI report is different. The case where multiple parameters are different is also included in this invention, and will not be listed one by one here.

[0152] In some embodiments, the first cell is a non-serving cell of the terminal, the second cell is a serving cell of the terminal, and the priority of the first CSI report is pre-configured to be higher than the priority of the second CSI report.

[0153] Optionally, if the first cell is a non-serving cell of the terminal, then the first CSI report corresponds to the CSI of the non-serving cell, for example, the first CSI report includes at least one of PMI, RI, CQI, LI, and CRI. If the second cell is the serving cell of the terminal, then the second CSI report corresponds to the CSI report of the serving cell. In this case, the priority of the first CSI report is directly higher than the priority of the second CSI report. That is, the priority of the first CSI report and the second CSI report can be determined without being based on the above information and formula (1).

[0154] In some embodiments, the first cell is a non-serving cell of the terminal, and the second cell is a serving cell of the terminal. The priority of the first CSI report and the second CSI report can also be determined based on the above information and formula (1). For specific examples, please refer to the embodiments when the first cell is a non-serving cell of the terminal and the second cell is a non-serving cell of the terminal, which will not be repeated here.

[0155] Step S2106: Based on the priority of each CSI report in the multiple CSI reports, do not update at least one CSI report with a lower priority among the multiple CSI reports.

[0156] In some embodiments, the lowest-priority CSI report among multiple CSI reports may not be updated.

[0157] In some embodiments, the priority of multiple CSI reports may not be sorted from high to low, and the last N CSI reports may not be updated.

[0158] In some embodiments, a subset of CSI reports may be updated according to their priority. Optionally, the CSI reports may be sorted from highest to lowest priority. Further, a subset of CSI reports may be identified sequentially from the multiple CSI reports and updated accordingly. It is understood that the total CSI processing unit occupied by the subset of CSI reports is less than or equal to the second CSI processing unit. Correspondingly, the remaining CSI reports other than the aforementioned "a subset of CSI reports" are not updated. It is understood that the priority of the "remaining CSI reports" is lower than the priority of the "a subset of CSI reports".

[0159] In some embodiments, multiple CSI reports are sorted in descending order of priority. Further, at least one of the multiple CSI reports is updated sequentially, that is, multiple CSI reports are updated sequentially from high to low. If the total number of CSI processing units occupied by the CSI reports being updated is greater than the second CSI processing unit supported by the terminal, the update is stopped, that is, subsequent CSI reports are not updated.

[0160] Understandably, since the first CSI processing unit exceeds the second CSI processing unit, the terminal may not update the low-priority CSIs in multiple CSI reports. In other words, the low-priority CSI report still contains the CSIs calculated or determined in the previous moment.

[0161] In some embodiments, the terminal uses the reference signal resources of the cell corresponding to each CSI report to perform CSI measurements according to the priority and measurement configuration of the CSI reports, so as to update the CSI reports. Optionally, the terminal can perform CSI measurements and calculations on multiple CSI reports according to their priority based on the reference signal resources configured in the CSI measurement configuration, so as to update the CSI reports with higher priority.

[0162] In step S2107, the terminal sends multiple CSI reports to the network device.

[0163] In some embodiments, after updating according to the priority of multiple CSI reports, the terminal sends multiple CSI reports to the network device. It is understood that the multiple CSI reports include CSI reports with different priorities, wherein the higher priority CSI report contains the updated CSI, while the lower priority CSI report contains the unupdated CSI report.

[0164] In some embodiments, the highest-priority CSI report among multiple CSI reports contains the updated CSI report, while the remaining CSI reports contain the unupdated CSI reports.

[0165] In some embodiments, a subset of CSI reports in a plurality of CSI reports contains updated CSI reports, while the remaining CSI reports contain non-updated CSI reports. It is understood that the subset of CSI reports has a higher priority than the remaining CSI reports, and the total CSI processing unit occupied by the subset of CSI reports is less than or equal to the second CSI processing unit.

[0166] In some embodiments, the terminal may send multiple CSI reports to the network device based on the CSI measurement configuration information in the second information. Optionally, the terminal may determine parameters such as the CSI report type, report content, report frequency, and report timing according to the CSI measurement configuration, and report the CSI according to the above parameters.

[0167] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2107. For example, step S2102 may be implemented as a separate embodiment, step S2104 may be implemented as a separate embodiment, step S2105 may be implemented as a separate embodiment, step S2106 may be implemented as a separate embodiment, and steps S2105+S2106 may be implemented as a separate embodiment, but are not limited thereto.

[0168] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0169] In this embodiment of the present disclosure, when the terminal determines that the first CSI processing unit occupied by multiple CSI reports within the same time unit is greater than the second CSI processing unit supported by the terminal, it can update the higher-priority CSI reports among the multiple CSI reports according to the CSI priority, and not update the lower-priority CSI reports. By not updating the lower-priority CSI reports, resource conflicts of CSI processing units can be avoided.

[0170] Figure 2B This is an interactive schematic diagram illustrating a communication method according to an embodiment of this disclosure. For example... Figure 2B As shown, this disclosure relates to a communication method for a communication system 100, the method comprising: Step S2201: The network device sends the first information to the terminal.

[0171] For optional implementations of step S2201, please refer to [link / reference]. Figure 2A Optional implementation methods of step S2101, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0172] In step S2202, the terminal determines the first CSI report and the second CSI report that need to be processed within the same time unit based on the first information.

[0173] In some embodiments, the first CSI report is a CSI report of at least one first cell, and the second CSI report is a CSI report of at least one second cell, wherein the first cell is a non-serving cell of the terminal, and the second cell is one of the serving cell and the non-serving cell of the terminal.

[0174] In some embodiments, the first cell is not currently the serving cell of the terminal; that is, the first cell is currently a non-serving cell of the terminal. It is understood that when the terminal determines the reference signal resources of the first cell, the first cell is not yet the serving cell of the terminal.

[0175] In some embodiments, the first cell can be one of the terminal's candidate cell, neighboring cell, and target cell. It is understood that when the terminal determines the first reference signal resource, the first cell is not yet the terminal's serving cell. For example, the first cell can be the cell to which the terminal is about to handover; after the terminal hands over to the first cell, that first cell becomes the terminal's serving cell.

[0176] In some embodiments, the second CSI report may be the CSI of the serving cell or it may not be the CSI of the serving cell. For example, the second CSI report may be a measurement report of L1-RSRP or L1-SNIR of a non-serving cell.

[0177] In some embodiments, where the first cell and the second cell are different non-serving cells, the first CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI. The second CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI.

[0178] In some embodiments, where the first cell is a non-serving cell and the second cell is the same non-serving cell, the first CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI. The second CSI report includes at least one of the following: none, CRI-RI-PMI, CRI-RI-i1, CRI-RI-i1-CQI, CRI-RSRP, CRI-SINR, SSB-Index-RSRP, SSB-Index-SINR, CRI-RI-LI-PMI-CQI, CRI-RSRP-Index, SSB-Index-RSRP-Index, CRI-SINR-Index, SSB-Index-SINR-Index, and TDCP. Alternatively, the second CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI. In this case, the reported amounts in the first and second CSI reports are the same.

[0179] In some embodiments, where the first cell is a non-serving cell and the second cell is a serving cell, the first CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI. The second CSI report includes at least one of the following: CRI-RI-PMI, CRI-RI-i1, CRI-RI-i1-CQI, CRI-RSRP, CRI-SINR, SSB-Index-RSRP, SSB-Index-SINR, CRI-RI-LI-PMI-CQI, CRI-RSRP-Index, SSB-Index-RSRP-Index, CRI-SINR-Index, SSB-Index-SINR-Index, and TDCP.

[0180] In step S2203, the network device sends the second information to the terminal.

[0181] For optional implementations of step S2203, please refer to [link / reference]. Figure 2A Optional implementation methods of step S2103, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0182] In step S2204, the terminal determines the third CSI processing unit for each of the first CSI report and the second CSI report, and determines the total first CSI processing unit occupied by the two CSI reports based on the third CSI processing unit.

[0183] In some embodiments, the third CSI processing unit occupied by the first CSI report relates to at least one of the following: The number of first cells corresponding to the first CSI report; The number of CSI-RS resources used for CSI measurements corresponding to the first CSI report; The number of ports of the CSI-RS resource corresponding to the first CSI report; The number of channel measurement resources used for CSI measurements corresponding to the first CSI report; The first type of CSI report; The number of reports submitted by the first CSI.

[0184] In some embodiments, the type of the first CSI report may include, but is not limited to, the following types set in the codebook: single-panel type I, multi-panel type II, port selection type II, type II, enhanced type II, and enhanced type II.

[0185] In some embodiments, the type of CSI reported by the first CSI can be a single CSI with wideband frequency granularity (CSI). single CSI with wideband frequency-granularity).

[0186] In some embodiments, the amount of data reported in the first CSI report can be any of the following: 'CRI-RI-PMI-CQI', 'CRI-RI-LI', 'CRI-RI-LI-PMI-CQI'.

[0187] In some embodiments, different reporting volumes of the first CSI report have different effects on the third CSI processing unit occupied by the first CSI processing unit. For example, the third CSI processing unit occupied by the reporting volume of the first CSI report being one of 'CRI-RI-PMI-CQI', 'CRI-RI-LI', or 'CRI-RI-LI-PMI-CQI' is different from the third CSI processing unit occupied by the reporting volume of the second CSI report being any of 'CRI-RSRP', 'CRI-SNIR', 'SSB-Index-RSRP', 'SSB-Index-SINR', 'CRI-RSRP-Index', 'SSB-Index-RSRP-Index', 'CRI-SINR-Index', or 'SSB-Index-SINR-Index'.

[0188] In some embodiments, the process of determining the third CSI processing unit occupied by the first CSI report may include: The number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement corresponding to the first CSI report, the number of ports of the CSI-RS resources corresponding to the first CSI report, the number of channel measurement resources for CSI measurement corresponding to the first CSI report, the type of the first CSI report, and the reporting volume corresponding to the first CSI report are determined. Based on at least one of the above information, the third CSI processing unit occupied by the first CSI report is determined.

[0189] In some embodiments, the number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement, the number of ports of the CSI-RS resources, the number of channel measurement resources for CSI measurement, the type of the first CSI report, and the reporting volume corresponding to the first CSI report can be determined based on the CSI measurement configuration corresponding to the first CSI report of the network device.

[0190] In some embodiments, the third CSI processing unit of the second CSI report is determined based on at least one of the following: The number of second cells corresponding to the second CSI report; The number of CSI-RS resources corresponding to the second CSI report for CSI measurements; The number of ports of the CSI-RS resource corresponding to the second CSI report; The number of channel measurement resources used for CSI measurements corresponding to the second CSI report; Types of second CSI reports; The number of reports submitted by the second CSI.

[0191] The number of second cells corresponding to the second CSI, the number of CSI-RS resources for CSI measurement corresponding to the second CSI report, the number of ports of the CSI-RS resources corresponding to the second CSI report, the number of channel measurement resources for CSI measurement corresponding to the second CSI report, the type of the second CSI report, and the reporting volume corresponding to the second CSI report are determined. Based on the above information, the third CSI processing unit occupied by the second CSI report is determined.

[0192] In some embodiments, after determining the third CSI processing units occupied by the first CSI report and the second CSI report respectively, the third CSI processing units occupied by the two CSI reports can be summed to obtain the total first CSI processing units occupied by the two CSI reports.

[0193] Step S2205: In response to the first CSI processing unit being greater than the second CSI processing unit supported by the terminal, the priority of the first CSI report and the second CSI report is determined.

[0194] Whether the first CSI report carries an indicator parameter for the first reported quantity. k =1; The CSI report configuration identifier corresponding to the first CSI report: In scenarios where CSI reports are configured using LTM-CSI-ReportConfig, s Indicates the CSI report configuration ID of LTM LTM-CSI-ReportConfigID ;otherwise, sThis indicates the CSI report configuration identifier.

[0195] The first CSI report corresponds to In scenarios where CSI reports are configured using LTM-CSI-ReportConfig, The maximum number of CSI reports configured for the upper-level parameter LTM (maxNrofLTM-CSI-ReportConfigurations). Otherwise, Indicates the maximum number of CSI report configurations.

[0196] Cell index corresponding to the first CSI report c In scenarios where CSI reports are configured using LTM-CSI-ReportConfig, c This is the index value of the serving cell configured in the configuration report. Otherwise, c This indicates the cell index of the serving cell for the terminal.

[0197] Based on the above information and formula, the priority of the first CSI report is determined.

[0198] In some embodiments, both the first cell and the second cell are non-serving cells of the terminal, and the priority of the first CSI report and the second CSI report can be determined based on the above information and formula (1).

[0199] Optionally, the first CSI report is a CSI of a non-serving cell, and the reported quantity in the first CSI report is at least one of PMI, RI, CQI, LI, and CRI; the second CSI report is also a CSI of a non-serving cell, and the reported quantity in the second CSI report is L1-RSRP or L1-SINR. All other values ​​in the formulas corresponding to the first and second CSI reports are the same, only the reported quantity differs. Based on the above formula (1), the priority value corresponding to the first CSI report is determined to be greater than the priority value corresponding to the second CSI report. Since a larger priority value indicates a lower priority, the priority of the first CSI report is lower than the priority of the second CSI report.

[0200] Optionally, the first CSI report is a CSI report for a non-serving cell, and the reported quantity in the first CSI report is at least one of PMI, RI, CQI, LI, and CRI; the second CSI report is also a CSI report for a non-serving cell, and the reported quantity in the second CSI report is also at least one of PMI, RI, CQI, LI, and CRI. The cell indices corresponding to the first CSI report and the second CSI report are different. For example, the cell index corresponding to the first CSI report is 0, and the cell index corresponding to the second CSI report is 1, while all other values ​​in the formula are the same, only the cell indices are different. Based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report. The larger the priority value, the lower the priority; therefore, the priority of the first CSI report is greater than the priority of the second CSI report.

[0201] Optionally, the first CSI report is a CSI report for a non-serving cell, and the reported quantity in the first CSI report is at least one of PMI, RI, CQI, LI, and CRI; the second CSI report is also a CSI report for a non-serving cell, and the reported quantity in the second CSI report is also at least one of PMI, RI, CQI, LI, and CRI. The LTM CSI report configuration IDs corresponding to the first CSI report and the second CSI report are different. For example, the LTM CSI report configuration ID corresponding to the first CSI report is 0, and the LTM CSI report configuration ID corresponding to the second CSI report is 1. All other values ​​in the formula are the same, only the LTM CSI report configuration IDs are different. Based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report. Since a larger priority value indicates a lower priority, the priority of the first CSI report is greater than the priority of the second CSI report.

[0202] It should be noted that the above only gives an example where only one value of each of the values ​​in formula (1) corresponding to the first CSI report and the second CSI report is different. The case where multiple parameters are different is also included in this invention, and will not be listed one by one here.

[0203] In some embodiments, the first cell is a non-serving cell of the terminal, the second cell is a serving cell of the terminal, and the priority of the first CSI report is pre-configured to be higher than the priority of the second CSI report.

[0204] Optionally, if the first cell is a non-serving cell of the terminal, then the first CSI report corresponds to the CSI of the non-serving cell, for example, the first CSI report includes at least one of PMI, RI, CQI, LI, and CRI. If the second cell is the serving cell of the terminal, then the second CSI report corresponds to the CSI report of the serving cell. In this case, the priority of the first CSI report is directly higher than the priority of the second CSI report. That is, the priority of the first CSI report and the second CSI report can be determined without being based on the above information and formula (1).

[0205] In some embodiments, the first cell is a non-serving cell of the terminal, and the second cell is a serving cell of the terminal. The priority of the first CSI report and the second CSI report can also be determined based on the above information and formula (1). For specific examples, please refer to the embodiments when the first cell is a non-serving cell of the terminal and the second cell is a non-serving cell of the terminal, which will not be repeated here.

[0206] Step S2206: Do not update the CSIs with lower priority in the first CSI report and the second CSI report.

[0207] In some embodiments, if the priority of the first CSI report is higher than that of the second CSI report, the first CSI report is updated, but the second CSI report is not updated.

[0208] In some embodiments, if the priority of the second CSI report is higher than that of the first CSI report, the second CSI report is updated, but the first CSI report is not updated.

[0209] For optional implementations of step S2206, please refer to [link / reference]. Figure 2A Optional implementation methods of step S2106, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0210] Step S2207: The terminal sends a first CSI report and a second CSI report to the network device.

[0211] In some embodiments, if the priority of the first CSI report is higher than that of the second CSI report, the first CSI report received by the network device is the updated CSI report, and the second CSI report is the unupdated CSI report.

[0212] In some embodiments, if the priority of the second CSI report is higher than that of the first CSI report, the first CSI report received by the network device is an outdated CSI report, and the second CSI report is an updated CSI report.

[0213] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2207. For example, step S2202 may be implemented as a separate embodiment, step S2204 may be implemented as a separate embodiment, step S2205 may be implemented as a separate embodiment, step S2206 may be implemented as a separate embodiment, and steps S2205+S2206 may be implemented as a separate embodiment, but are not limited thereto.

[0214] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0215] In this embodiment, when the terminal determines that the first CSI processing units occupied by the first CSI report and the second CSI report within the same time unit are greater than the second CSI processing units supported by the terminal, it updates the CSI report with higher priority than the second CSI report, and does not update the CSI report with lower priority. By not updating the lower priority CSI report, resource conflicts of CSI processing units can be avoided. Especially in the scenario where the first cell is a non-serving cell and the second cell is a serving cell, since the first cell has a higher priority, the CSI of the first cell can be updated in real time. When the first cell becomes the new serving cell of the terminal, the network device can perform timely and accurate scheduling for the terminal based on the first CSI report, improving the efficiency and speed of data transmission and increasing the decoding success rate.

[0282] The following is an exemplary description of the above method, and this disclosure provides a communication method.

[0283] In some embodiments, the terminal determines that a first CSI report and a second CSI report need to be calculated in the same symbol, and determines the first CSI processing unit required for calculating the first CSI report and the second CSI processing unit required for calculating the second CSI report. If the number of first and second CSI processing units exceeds the number of CSI processing units that the terminal can support, the terminal does not update the lower-priority first or second CSI report. The first CSI report is the CSI report corresponding to a first cell, which is not the terminal's serving cell.

[0284] In some embodiments, the first cell may be referred to as a candidate cell, a neighboring cell, a target cell, etc.

[0285] In some embodiments, "the first cell is not currently the serving cell of the terminal" means that when the terminal determines the first reference signal resource, the first cell is not yet the serving cell of the terminal. However, it is possible that the first cell is the cell to which the terminal will hand over next, and after the handover, the first cell becomes the serving cell of the terminal.

[0286] In some embodiments, the second CSI report may be a CSI report of the serving cell, or it may not be a CSI report of the serving cell (such as a measurement report of L1-RSRP or L1-SINR of a non-serving cell).

[0287] In some embodiments, the first CSI report includes at least one of the following: PMI: precoding matrix indicator; RI: rank indicator; CQI: channel quality indicator; LI: layer indicator; CRI: CSI-RS resource indicator.

[0288] In some embodiments, the first CSI processing unit occupied by the first CSI report relates to at least one of the following: The number of first cells corresponding to the first CSI report, wherein the size of the first CSI processing unit is proportional to the number of first cells; The number of CSI-RS resources, or channel measurement resources, corresponding to each first cell, wherein the size of the first CSI processing unit is proportional to the number of CSI-RS resources or channel measurement resources of the first cell; The type of CSI for the first cell is which of the following: (1) codebookType is set to 'typeI-SinglePanel','typeI-multiPanel','typeII-PortSelection','typeII','enhanced typeII-PortSelection', 'enhancedtypeII '.

[0289] (2) single CSI with wideband frequency-granularity.

[0290] The number of reports submitted by the first CSI is any one of the following: 'cri-RI-PMI-CQI', 'cri-RI-i1', 'cri-RI-i1-CQI', 'cri-RI-LI-PMI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR', 'cri-RSRP-Index', 'ssb-Index-RSRP- Index', 'cri-SINR- Index', 'ssb-Index-SINR- Index'.

[0291] The first CSI report measures whether the number of ports of the corresponding CSI-RS resource is greater than 4.

[0292] In some embodiments, the network device configures a reference signal resource corresponding to the first CSI report measurement.

[0293] In some embodiments, the priority of the first CSI report is determined.

[0294] The priority value is determined based on the following:

[0295] in, for aperiodic CSI reports to be carried on PUSCH; for semi-persistent CSI reports to be carried on PUSCH; for semi-persistent CSI reports to be carried on PUCCH; for periodic CSI reports to be carried on PUCCH; for CSI reports carrying L1-RSRP or L1-SINR; for CSI reports not carrying L1-RSRP or L1-SINR; c is the serving cell index and is the value of the higher layer parameter maxNrofServingCells ; s is the reportConfigID and is the value of the higher layer parameter maxNrofCSI-ReportConfigurations ; In some embodiments, the first CSI report reports k The value of is 1; In some embodiments, the first CSI report s and for: for a CSI report configuredwith LTM-CSI-ReportConfig , s is the LTM-CSI-ReportConfigID and is the value of the higher layer parameter maxNrofLTM-CSI-ReportConfigurations .

[0296] In some embodiments, the first CSI report c , for a CSI report configured with LTM- CSI-ReportConfig , c is the serving cell index value where the report configuration is configured.

[0297] In some embodiments, different CSI priorities that are all first cells can be determined based on a priority formula.

[0298] In some embodiments, the second CSI report may be a CSI report of a non-serving cell.

[0299] In some embodiments, the second CSI report includes at least one of the following: 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR', 'cri-RSRP-Index', 'ssb-Index-RSRP-Index', 'cri-SINR-Index', 'ssb-Index-SINR-Index'.

[0300] In some embodiments, the first CSI report is a CSI of a non-serving cell, and the second CSI report is a CSI of the serving cell. The first CSI report has a higher priority than any CSI of the serving cell; that is, the first CSI report has a higher priority than the second CSI report of the serving cell.
